Description
Product Overview of PCI-E 3.0 X8 SAS/SATA Raid Controller
The HP 643379-001 Smart Array P822 is a PCI-E 3.0 X8 SAS/SATA RAID controller with 2GB FBWC. This means that it is a hardware device that manages multiple hard drives or SSDs, allowing them to operate as a single logical unit. This controller can be used in servers and workstations to improve performance and reliability by providing fault tolerance and redundancy.
RAID Controller
RAID stands for Redundant Array of Inexpensive Disks. It is a method of combining multiple hard drives or SSDs into a single logical unit for improved performance, reliability, and data protection. RAID controllers are hardware devices that manage the RAID configuration and provide data caching and other features.
RAID controllers can be implemented in software or hardware. Software RAID is typically implemented in the operating system, and it relies on the CPU and memory to manage the RAID configuration. Hardware RAID, on the other hand, is implemented in a separate device that offloads the RAID management from the CPU and memory, providing better performance and reliability.
Features of the HP 643379-001 Smart Array P822
The HP 643379-001 Smart Array P822 is a hardware RAID controller that supports up to 24 internal SAS or SATA hard drives or SSDs. It provides advanced RAID features such as RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50. It also supports online RAID expansion and migration, which allows you to add or remove hard drives from the RAID configuration without losing data.
The P822 features a PCIe 3.0 x8 interface, which provides a high-speed data transfer rate of up to 8 GT/s. It also has a 2GB flash-backed write cache (FBWC), which provides improved performance by caching frequently accessed data in memory. The FBWC also protects data in the event of a power loss or system failure, by storing cached data on the flash memory.
The P822 supports HP SmartCache, which is a feature that allows you to use an SSD as a cache for frequently accessed data. This can significantly improve performance, especially for applications that require a lot of random access to data.
The P822 supports HP Smart Array Advanced Pack (SAAP), which is a set of advanced RAID features that provide additional data protection and performance. SAAP includes features such as RAID 6+0, which provides both double parity and striping for improved performance and fault tolerance, and Advanced Data Mirroring, which provides real-time data mirroring between two RAID arrays.
Benefits of using the HP 643379-001 Smart Array P822
